CUSHION -H EEL.

To all crhom z'tmay concern; a Be it known that we,Rom:nr SJQRAHAM and'Baritone l llloRsic, both citizens of the United States, the said GRAHAMresiding in the city of New York, borough ofMan-- hattan, county andState of New York, and the said Morse residing inth'e city' of New York,borough of Brooklyn, county of and a soft or cushion material, thetwoinn-- terials beingso combined and related that the lower part of theheel is free to havea.

limited movementwith respect to the solid part and thecushionmaterial...

The objects of the. invention are, to enable the heel-to be attached tothe shoe ,by the ordianaryheeling machinery now'so extensively used'inshoe; factories; second,-

to minimizethe quant-iy of rubber, or other cushionmateriahiconsistentwith the attain ment; of the purposes of; theinvention; 4 third,toso securely attach the several parts reclude theiraccidental separation even siouldthe yieldable part of the heelas tobecome caught in thefact'ofwalking, and to provide for thefexpediti'ousandeconomr cal manufacture and attachment v article. i

The invention-'is' embodied in-ah eel onepart of which is composed ofsolid material so formed that'the top lift, or in reality such as rubberorrubber compound.

The umnufactnre of the heel, from a practical standpoint, an'd byexisting machinery and in accordance with existing methods', involvesthe 'assen'il'ilage and attachment in:

-two sections and with a top lift, the latter consti'uiting a thirdsection. The first section isattachrd-"as -ordinarily practised in theart; the second section isformed to carry out this invention, i. clbyprovidin a 'bo'om layer composed. in part of soil material (leather) andin part. of rubber or cushion material, after which the 'c'ompletesecond section is attachedflhyfnailing Specification of Letters Patent.v "Application filed September 6, 1912".

Patented May 6, 1913.

the solid part, including the half leather section, firmly tothefirstfsection, the nails being allowed to protrude, and 'finally thetop lift (or bottom piece) is -positioned andattached by the protrudingpurts of the nails. v r

Inithe accompanying drawings, we havelllustrated different practicalembodiments of the invention, but the Iconstruct-ions showh therein areto be understood .as illustrative, only, and not as defining the limitsof the invention. c

Figure 1 is a bottom plan view of a heel constructed in accordance withthis inventlon. Fig. 2 is avertical section taken longitudinal] throughthe heel illustrating one form oft e partlayer of cushionrnaterial.

Fig. 3 is a vertical longitudinalfsection illustrating another form ofthe layer of cushon material.

A designates a portion of ashoe" sole, and

BI-i'sf'the heel, This heel is composed of relatively hard material and,a, layer or sec- *tion of cushion material, The heel is at- -tached in.two or three sections, one of which is composed. of a; series]offlayerjs' 3 a." The- ,second section is composetho'f a part.'layerorlayers'of hardniaterial,ashb b and a part layer: of cushion;material,; as; .0, and a lift id, whereas the third section .ortop'lift'c'om As shown lnFig; :2, the second section embodies a'laver'cofcushion material which is ,equali' in t ickness to t'wo layers 1) bot leatheig the-two layers 1) b and the'rubber.

layer a being each equal in area to one half the area of the lift'a',althoughvthe relative proportions of the part a to the parts 6 7)composing-the .second section may be varied as desired. Furthermore, therubber section c may be-' equal in thickness to a layer 6 so that onlyone layer 7) need be used, but i t-is preferred to, employ a cushionlayers substantiallyequal in thickness to the two leather layers'b b.Inthe manufacture of the shoe, the first sectioncomposed ofthe layers,a' a-are':fastened to-- gether and attached .tothe' sole at the heelportion-inthefordinary way and by existmg machineryq The second sectionconsist-"- ing of the parts?) I) c (l are-assembled so that --a-'c11sh1on layer'o is imposed directly' againstthe'layerd and the pleces b are1 positioned one upon the other and against a part of. the.layer d. Thecushion layer 0 is attached in any suitable way as cement- I ing it tothe layer (Z, whereas the layers]; 6 are attached to the layer 61 bynailing the parts together, the ends of the nails protruding in theusual method-of making heels by existing machinery.

It should be understood that the parts (I) b a d) composing the secondsection should be assemble as is the, second section of an ordinaryheel. In the process of attaching the second section to the firstsection; said second section can he handled and applied with the samefacility and advantage as the second sections, of ordinary heels.

The nails which fasten the first section of the shoe are indicated at e,and these-nails c are independent of the nails which attach the secondsection and the top-lift or bottom layer (1 to the first section.

In carryingthe present invention into practice, the second section andthe top'liftare not nailed in the ordinary way, but on,

the contrary nails 7, g, 7). are employed, said nails being sopositioned that the rear part of the layers d ll will be free orunattached.

I Nails are at the respect-ire sides ofthe heel, nails in are at thefront edge thereof, whereas nails g are across thebreastof the heel, allthe nails f, g, It being forwardly of the rear part of the heel which isto remain free and unattached. Nails h are driven through the first andsecond sections at the forward part thereof; nails f are at therespective sides of. the heel and are driventhrough the first and secondsections, where as nails garedriven through the first and secondsections forwardly of the rear part of the layers (2 (1, said nails 9beingdriveltthrough the cushion layer 0, but in this connectionjt is tobe noted that the nails f g 71 are not'driven home in attaching thesecond section to the first section the ends of the nails being allowedto protrude below layer Z so that the protruding ends of the nails areutilized in fastening the top lift or bottom layer (l to the heel.

It evident that the layers 1) b d of the second section will be attachedsolidly and firmly to the first sect-ion by the nails 7 g 71, but therear part of lifts (Z at will be unatta'chcd so as to allow said rearparts of the two lifts to have a certain limited freedom of play, forthe purpose of securing the desired cushion effect in connection withthe layer c. The employment of a layer 0 which is equal to substantiallyone half the area of either of the lifts a d d provides for economy inthe use of rubber required 'to produce composite heels of thisinvention,

Copies of this patent may be obtained for but at. the same time theimportant advanlarge is secured in the use of the sections Z) I) inconnection with a half layer 0 of rubber. for the reason that theforward part of the heel may be nailed as firmly and solidly together asan ordinary leather heel, as a result of which the heel of thisinvention is capable of manufacture by existing heel machinery and inaccordance with the well known methods, but at the same time the heelwhen attached is so secure and firm that it cannot become displacedaccidentally, or. torn-off except by extremely rough usage.

In Fig. 2 the cushion layer has a straight forward edge and it is ofuniform thickness so that the forward edge of the layer 0 abuts squarelyagainst the straight reaiwcdges of layers 7) 7', but in the embodimentshown in Fig. 3 of the drawings, the cushion layer 0 is tapering, thusfurther reducing the quantity of'rubber required. Accordingly. thelayers 6 if'are tapered at. their rezr edges in order that the taperinglayer c may substantially overlap the tapering edges of the layers 1)6*. Otherwise the heel is constructed and attaelwd in the manner aud" bythe meanshereinbet'ure described f i In connection-with the'salieutfeatures of economy of manufacture and security of attachmentof theheel,- it is desired to state that the rubber layer a or c 'is' fastenedse curely in place at its forwardedge only by the row of nails 9' whichare positionedat the breast of'the heel, and thus therubber layer cannotwork loose or become detached from the heel. r v

Having thus fully described tlKillVtllilOll, what we claim as new, anddesire to secure by Letters Patent is: i

A heel embodying an upper member composed of solid material, a layercomposed partlyof non-yielding material audpart-ly of cushion mater'zl,both of said parts-being in the same horizontal plane. one or more liftsbelow the two part layer. and attaching means extending into the bottomlift or lifts andthe solid material of the two part lift andalso throughthe forward part of the cushion material, leaving free or mint- 3 tachedthat. part of the bottom lift or lifts below the cushion material.

In testimony-whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
